SUMMARY
Brittle materials fail to achieve their theoretical tensile strengths primarily due to the presence of defects and the influence of the stress intensity factor. Ductile materials, on the other hand, do not reach their theoretical shear strengths because their failure mechanisms are influenced by plastic deformation and the material's microstructure. Understanding these concepts is crucial for predicting material behavior under stress and optimizing material selection in engineering applications.
